Genus Staticc as represented at Biakeney Point. I. 245 
to prolonged periods of salt marsh conditions, while at other times they will 
approximate more nearly to those of the flanks of the laterals. It is in 
accordance with this unusual combination of factors that one meets in 
the anatomy a mixture of characters in many respects recalling, on the one 
hand, those of the closely related S. binervosa , and on the other, those of 
the typical salt marsh forms such as S. Limonium . 
It is of interest to note that Long 1 gives the habitat of 5 . bellidifolia in 
the adjacent marshes at Wells as rolling sand-covered knolls 2 to 3 ft. 
above the highest spring tides. The much larger size of these specimens 
here and at Burnham Overy is probably due to the great depth of the sandy 
mud in which they grow as compared with the shallow mud overlying the 
shingle in the Biakeney ‘ lows \ 
In the region of the Long Hills and on the shingle plateau on the 
north-west side of the upper reaches of the Pelvetia marsh, where it ap- 
proaches the main shingle bank, the localities of binervosa and bellidifolia 
overlap to a certain extent, and in these regions a form of S. binervosa 
occurs which differs in certain respects from the typical one. In many 
features, both morphological and anatomical, this form, distinguished as the 
‘ broad-leaved binervosa ’ in contradistinction to the typical narrow-leaved 
plant, is intermediate between .S', binervosa and .S', bellidifolia . 2 There is 
a possibility that we are dealing with a hybrid between the two, though 
attempts to raise the plant from seed have so far failed. The broad-leaved 
type is entirely absent from the region of the Marams, where also only 
.S', binervosa occurs, and is restricted to those regions where the possible 
parent species are both present. 
In addition to the plants whose habitats have been briefly described 
above, plants from experimental garden cultures started by Dr. E. J. Salis- 
bury have also been examined, more particularly .S', binervosa plants grown 
in a cold greenhouse, and plants raised from seed. 
A summary of the chief forms of S', binervosa examined is as 
follows : 
1. Tall Form — luxuriant plants growing on the edge of a shingle fan, 
termed £ Main bank plants \ 
2. Dwarf Form — (PI. VI, Photo 1) — 
(a) Typical S', binervosa plants from the lateral shingle banks, termed 
‘ narrow-leaved binervosa ’. 
(b) Plants from the margin of the muddy shingle lows, termed ‘ mud 
plants ’. 
(<r) Plants from sandy shingle lows, termed £ sand plants \ 
(d) Plants from the experimental areas on the lateral shingle banks.
